The objectives of this work were 1) to compare the goodness-of-fit of empirical models of the lactation curve and 2) to analyze the factors affecting the shapes of the lactation curves, the parameters describing them, and the overall milk yield of Latxa dairy sheep. A total of 14,699 records from...

Samples of fibre were taken from sheep (n = 45) and goats (n = 24) of the West African Dwarf (WAD) and northern breeds in Nigeria. Three types of coat were noted in sheep: fine woolled, double coated and predominantly hairy. Median fibre diameters were 14.9, 75.7 and 93.3 µm, respectively. Goats ...

Sheep in the cool highlands of central-northern Ethiopia (Menz) are of the meat type, have coarse wool, and are often perceived to be low in productivity. To increase their productivity, they have been upgraded with Awassi sheep. The aim of this study was to compare the performance of 37.5% Awass...

In an examination of the productivity of goats and sheep on a Maasai group ranch in Kenya, estimated least-squares means for pre-weaning mortality were 28.6% for goats and 32.1% for sheep. Three productivity indices based on total live weight of young produced per female per year, per kg female p...

Shugor, Dubasi and Watish sub-types of Sudan Desert sheep were evaluated on the basis of 3 productivity indices (weight of lamb weaned/ ewe/yr, weight weaned/kg ewe/yr and weight weaned/kg 0.75/ewe/yr). Components used to construct the indices were litter weight at 120 d, parturition interval, su...

This study was undertaken to investigate the genetic stability of an unselected Conlrol Group of South African Merino sheep and genetic change in a flock selected for increased clean fleece mass (Selection Group) under the same environmental conditions. Data regarding 14-17 months clean fleece ma...

A study was made of the levels of oestrous activity of two indigenous breeds of sheep (Somali and Nandi) and three exotic breeds of sheep (Merino, Karakul and New Zealand Romney Marsh) over a period of 3 years, in an equatorial environment. Breed was the only significant source of variation for t...
